The coil of the conventional dry air-core reactor is wound by electromagnetic wires, reinforced by epoxy resin glass fibers, clamped together by high-strength aluminum alloy star-shaped frames at two ends, and the whole glass fiber belt is tensioned and solidified and formed by a drying and dipping process. The coil is usually wound by parallel connection of a plurality of wires with diameters not exceeding 5mm, and turn-to-turn insulation is usually realized by adopting modes such as film wrapping, enameling and the like. When the air core reactor with small wire diameter needs to work under the high current of 20kA, the volume of the air core reactor is extremely large, and heat generated by loss is led out through a heat conducting medium in the air core wire, so that a large heating value is generated.
Therefore, when the equipment operation heat dissipation condition is relatively poor, the heat generated by the air-core reactor can not be effectively dissipated in time, and the temperature of the air-core reactor is too high, so that the insulating layer of the product is damaged to cause short circuit, and a burning accident occurs.
